Yes, we noticed that the Azorean author of "A Trip to the Azores" traveled there in 1867.
Interestingly, while his wife's name was Grace, her sister Nancy Madigan is discovered in the passenger lists as having also traveled to the Azores Islands, although it is not clear why would Nancy go there and whether she was traveling with her sister's husband. And where was Grace?
There are not enough facts available at the moment to form a complete picture of this point.
